The West Jambi KSO is located in the northern part of the hydrocarbon-rich South Sumatra basin, tectonically known as the back-arc basin. The asset is split into two areas; West Jambi I and West Jambi II. The block sits in a proven region for oil and gas exploration with transportation infrastructure nearby, such as the Trans Sumatra Pipeline, which directly intersects the asset.

In June 2011, Eneco Energy executed a KSO agreement with Pertamina, giving the company the rights to explore and exploit the asset for 20 years.

Eneco Energy controls 100% working interest and is the operator of the West Jambi KSO.
